DeFer-2
Based on 1 Customer Validation
DeFer-2 is a ferritin PROTAC degrader (Kd = 17.1 μM). DeFer-2 induces ferritin degradation, triggering caspase 3-GSDME-mediated pyroptosis in cancer cells through free iron accumulation and elevated ROS. DeFer-2 significantly inhibits tumor growth and prolongs survival in mice bearing B16F10 subcutaneous tumors. DeFer-2 can be used to study melanoma.
(Pink: Ferritin ligand (HY-N1446); Blue: VHL ligand (HY-125845); Black: linker (HY-N0067)).

DeFer-2 (0-5 μM, 0-24 h) reduces the ferritin expression by forming a ternary complex with ferritin and VHL, induces disruption of redox and mitochondrial homeostasis in B16F10 cells[1].
DeFer-2 (5 μM, 8-24 h) initiates caspase 3-GSDME-mediated pyroptosis through free iron accumulation and ROS elevation in B16F10 cells[1].
DeFer-2 (24-48 h) causes severe cytotoxicity to B16F10 cells with IC50s of 3.1 and 1.5 μM for 24 and 48 h, respectively[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.20 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.20 mM); Suspended solution
